[PATCH v2][next] wifi: wil6210: Annotate a couple of structs with __counted_by()

["Gustavo A. R. Silva" <gustavoars@kernel.org>]

Prepare for the coming implementation by GCC and Clang of the __counted_by
attribute. Flexible array members annotated with __counted_by can have
their accesses bounds-checked at run-time via CONFIG_UBSAN_BOUNDS (for
array indexing) and CONFIG_FORTIFY_SOURCE (for strcpy/memcpy-family
functions).

Signed-off-by: Gustavo A. R. Silva <gustavoars@kernel.org>

Changes in v2:
 - Annotate one more struct.
 - Update Subject line.
